SPRING-WHEEL Specification of Letters Patent.

Patented June 6, 1916.

Application filed May 29, 1915. Serial No. 31,196.

1 '0 all whom it may concern:

Be it known that I, KARL GEORG ERNST Morin, a subject of the Emperor of Germany, residing at Vancouver, in the Province of British Columbia and Dominion of Canada, have invented certain new and useful Improvements in Spring-WVheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends certain new and useful improvements in spring wheels and has for its primary object to provide a device of this character which will be of extremely simple construction and operation as well as highly efficient in use and cheap to manufacture.

Another object is to provide a spring wheel which will be composed of the minimum number of parts including a movable metallic casing with a rubber covering positioned over the felly of the Wheel and resiliently retained in normal position.

A further object of this invention is to provide a device of this character in which the metallic casing will be provided with removable inwardly directed flanges and means engaged with said flanges and with the felly to resiliently retain the metallic casing and the tread covering formed of rubber or other suitable material, in normal position.

\Vith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention reference is to be had to the follow ing description and accompanying drawings, in which Figure 1 is a fragmentary side elevation of a wheel constructed in accordance with my invention, and Fig. 2 is a transverse sectional view shown in perspective.

Referring in detail to the drawings by numerals, 1 designates the spokes which have their outer ends secured in the felly 2 in any suitable manner, while 3 designates the sectional metallic casing which has the reduced edges 3', said casing being secured around said felly 2 and connected to the reduced portion 3 of the metallic casing 3 are the annular members i which have the reduced portions 4C for connection with the reduced portions 3 of the metallic casing and having secured to their outer faces the inner ends of the helical springs 6, the other ends of which are secured to the inner periphery of the felly 2, outwardly of the spokes 1.

It will be readily seen that any number of helical springs 6 may be employed and will serve to resiliently retain the annular members at and casing 8 in normal position with the main or central portion of said.

casing spaced from the periphery of the felly 2. It will also be readily seen, by referring to the drawings, that the bolts 5, after passing through the reduced portions of the annular members 4 at right angles to the main portions of the casing 3, are extended through the tread covering 7 formed of rubber or other suitable material and engaged over the casing 3, as clearly shown in the drawings, the tread covering 7 being of substantially the same form as the casing 3 and being held in position against said casing and protected by the protecting strips 8 secured to the outer face thereof along the opposite edges of said covering and secured against movement by the bolts 5, previously mentioned, which also extend through said strips 8.

From the foregoing it will be clearly apparent that I have provided a spring wheel which will be of extremely simple and cheap construction, as well as highly eflicient in use, and as the annular members for the felly casing are removably secured in position and the casing formed in sections, the parts of the device may be readily assembled, and should any of the parts become worn or broken, they may be easily replaced at a small cost.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the details of construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed, or sacrificing any of the advantages thereof.

What is claimed is 1. A device of the class described including a felly, a sectional casing engaged around said felly and having a central portion spaced from the outer periphery of said telly, said casing having its edges reduced, annular members having reduced portions connected to the reduced edges of said casing a covering for said casing, protecting strips positioned against the edges of said covering, means engaged through the strips, covering and the reduced portions of the annular members and the casing for holding the same together, and a plurality of helical-shaped springs being secured between the annular members and the telly for resiliently retaining the casing in its normal position.

2. A device of the class described including a telly, a metallic casing for said felly and having a central portion spaced from the outer periphery of said telly, said casing having its edges decreased in thickness forming flanges and shoulders interiorly of said casing, annular members having en- Copies of thin patent may be obtained for siliently retaining the casing innormal position. when in use.

In testimony whereof I afiiX my signature in presence of two Witnesses.
